what is the difference between a1c and blood sugar

The A1C test and blood sugar (glucose) tests measure different aspects of your blood sugar levels:

• A1C Test:

  • Measures your average blood sugar levels over the past 2-3 months.
  • Reflects the percentage of hemoglobin in your red blood cells that has glucose attached to it.
  • Used to diagnose prediabetes and diabetes, and to monitor long-term blood sugar control.
  • Results are reported as a percentage (e.g., 5.7% for prediabetes, 6.5% or higher for diabetes).

• Blood Sugar Test:

  • Measures your current blood sugar level at the time of the test.
  • Often done with a finger prick or blood draw.
  • Used for daily monitoring, especially for people with diabetes, to manage insulin and diet.
  • Results are reported in mg/dL (e.g., 126 mg/dL or higher indicates diabetes).

In summary, the A1C test provides a long-term view of blood sugar control, while blood sugar tests give a snapshot of your current levels.
